Granted: 1987-01-22
Abstract: A mixed phenyl/mesityl phosphate ester composition that is useful as a fire retardant additive, having a phosphorus content of from about 8.2% to about 8.4% is prepared by reacting with agitation at about 120°C to 130°C distilled still bottom phenols with phosphorus oxychloride in the presence of a Friedel-Crafts catalyst to form a reaction product containing a substantial quantity of monoaryl phosphodichloridate and diaryl phosphochloridate. This reaction product is then further reacted at an elevated temperature with sufficient phenol to form a triaryl phosphate ester mixture. The mixed phenyl/ mesityl phosphate ester so obtained remains a liquid at room temperature over a substantial period of time.

Granted: 1987-08-27
Abstract: Methods and compositions are provided for preparing stabilized interferons and for combining stabilized interferon with cigarettes. Special domains of the interferon molecule are recognized by methods which are described. A means for constructing these domains by recombinant DNA technology is detailed. A method for stabilizing natural interferons is also described. A process for combining the stabilized interferon with cigarettes is presented. The combination of interferons and cigarettes is synergistic, especially because interferon effects are magnified at elevated temperatures and because interferon has a preferential effect on tumor cells, but for other reasons as well. The process is not obvious and will be beneficial to a large segment of mankind; those who use tobacco products.

Title: Winding a package of tape
Inventor: O'CONNOR LAWRENCE
IPC: B65H18/16
Filed: 1984-07-19
Granted: 1988-07-14
Abstract: A package of tape is formed with flanged portions built up at the ends and a central helical traverse portion. The flanged portions are effectively formed by a plurality of separate spiral windings each of which is interlocked with each other and the central traverse portion. The central portion is formed from a plurality of helical traverses with reversal positions slightly inside the inner edge of the flanged portions. Either the central traverse portion or the flanged portions is built up first to form a step following which the other is built up to meet the step. The step cannot be so high that the tape cannot traverse the step. The extreme ends of the package is thus formed by the stable spiral windings while edge drop-off from the ends of the traverse portion is limited to height of the last helical traverse.

Abstract: A bottle with a neck (1) has a child-resistant screw closure cap (13). In order to make the cap (13) child-resistant, the neck (1) is fitted with a collar (7) of U-shaped cross- section. The collar (7) is retained on the neck (1) by engagement of pawls (11) inside a portion (8) of the collar under a retaining ring (2) on the neck (1). The cap (13) is screwed onto the part (8) of the collar and to allow this to be done, the collar (7) is prevented from rotating on the neck (1) by engagement of the pawls (11) with ratchet teeth (4) on the outside of the neck (1). The pawls (11) and the ratchet teeth (4) are so shaped that if an attempt is made to unscrew the cap (13) merely by turning it in a counter-clockwise direction as seen from above, the pawls (11) ride over the ratchet teeth (4) so that the collar (7) is lifted on the neck (1) and is free to rotate. To enable the cap (13) to be unscrewed, the cap must be pressed downwards while it is rotated in a counter-clockwise direction to hold the pawls (11) in engagement with the ratchet teeth (4) and thus prevent the collar (7) from turning on the neck (1).

Abstract: A method of compression molding powders of metals, ceramics and the like. A thin rubber bag is adhered to the inside of a cavity formed within a permeable mold support so as to define a mold therein and the bag is packed with a raw material powder. The powder in the bag is evacuated to a degree of vacuum to compactly compress it and the rubber bag is sealed. In this condition, the compressed powder is removed from the support and compression molded to a higher degree of denseness by the CIP process. The inflation adhesion of the rubber bag to the inside of the support cavity is effected by reducing the pressure outside the permeable support.

Abstract: A firing mechanism with safety device for firearms, especially sport and hunting rifles and shotguns, with at least one barrel and a firing pin associated therewith and operable by way of a striker member in that the member is movable into an uncocked position, under the influence of the force of a compressed spring, against the firing pin after a trigger lever locking the striker member in a cocked position has been placed into a release position, and with at least one trigger with an associated rocker arm. In order to secure the firearm against unintended firing of shots due to external impact effects, the striker member is fashioned as a slide and is displaceable in the longitudinal direction from a rearward cocked position into a forward uncocked position. The trigger lever has an angled, curved, or like configuration and is arranged at the striker member so that it extends in the longitudinal direction and is pivotable about an axial support in such a way that, in the cocked position, the rear end of the trigger lever is secured by the rocker arm and the front end of the trigger lever rests in the forward direction on a stop fixedly formed within the frame and locks the striker member in the cocked position; this locking action being releasable by freeing the rear end of the trigger lever by way of the trigger-operated rocker arm and pivoting the trigger lever in such a way that the support of its front end at the stop is eliminated.
